[0002] A speed reducer is a key component for transmitting power and is widely used in various mechanical equipment. Its main function is to reduce the output speed of a motor and increase the output torque through gear transmission to meet the transmission needs of different mechanical equipment.

[0003] During use, the speed reducer requires flanges to be installed on the outer walls of the motor and the speed reducer body to connect and fix them together. This process uses bolts and nuts to connect the motor and the speed reducer. However, during long-term operation, the vibration generated during operation will be transmitted to the flange. After long-term use, some of the fixing bolts on the flange will loosen, affecting the connection between the speed reducer body and the motor. Utility Model Content

Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 6As shown, this utility model can be implemented through the following embodiments: A speed reducer with an anti-loosening structure includes a speed reducer body 1, a flange 2 is provided on the speed reducer body 1, a plurality of connection holes 21 are provided on the flange 2, bolts 3 are installed on the connection holes 21, nuts 4 are installed on the bolts 3, a first mounting groove 22 and a second mounting groove 23 are provided on both sides of the connection holes 21, a fixing plate 5 is installed on the first mounting groove 22, a first storage groove 51 is provided on the fixing plate 5, a locking plate 6 is installed on the second mounting groove 23, a second storage groove 61 is provided on the locking plate 6, the fixing plate 5 and the storage plate are used to limit and fix the bolts 3 and nuts 4.

[0015] The locking plate 6 is inserted into the mounting slot 22 to store the bolt 3 through the storage slot 61, preventing the bolt 3 from loosening accidentally; the fixing plate 5 is inserted into the mounting slot 23 to store the nut 4 through the storage slot 61, preventing the nut 4 from loosening due to the loosening of the bolt 3, and together with the locking plate 6, the bolt 3 and nut 4 are limited and fixed.

[0016] like Figure 5 As shown, a through hole 62 is provided on the storage slot 2 61, and the diameter of the through hole 62 is the same as the diameter of the bolt 3. The through hole 62 is provided so that if the bolt 3 is too long and the fixing plate 5 cannot be installed, the through hole 62 allows the excessively long bolt 3 to pass through, which facilitates the installation of the fixing plate 5.

[0017] like Figure 2 , Figure 4 and Figure 5 As shown, a slot 211 is provided on the mounting groove 22, and a locking block 52 is installed inside the fixing plate 5. A spring 53 is installed between the locking block 52 and the fixing plate 5. The slot 211 and the locking block 52 cooperate to install the fixing plate 5 in the mounting groove 23, completing the connection between the fixing groove and the flange 2. The spring 53 is provided to push the locking block 52 away from the slot 211, making it easy to disassemble and replace the damaged fixing plate 5.

[0018] like Figure 2 , Figure 5 and Figure 6 As shown, the fixing plate 5 has a pressing groove 54, and the locking plate 6 has an insert rod 63 extending from it. A corresponding slot 24 is provided between the first mounting groove 22 and the second mounting groove 23. The insert rod 63 is used to insert into the pressing rod, thereby pushing the locking block 52 to compress the first spring 53, causing the locking block 52 to engage in the slot 211, thus achieving a fixed connection between the fixing plate 5 and the flange 2. The slot 24 is used to guide the insertion of the insert rod 63, facilitating the installation of the locking plate 6.

[0019] like Figure 1 , Figure 2 and Figure 6As shown, the locking plate 6 has fixing holes 64 and 62, and the flange 2 has screw holes 25. A screw 7 is inserted between the fixing hole 64 and the screw hole 25. The locking plate 6 is fixed to the flange 2 through the fixing hole 64 and the screw hole 25 and the screw 7, and further realizes the fixed connection between the fixing plate 5 and the flange 2. The screw 7 facilitates the disassembly and replacement of the locking plate 6, while ensuring a stable connection between the locking plate 6 and the flange 2.

[0020] like Figure 2 and Figure 6 As shown, a second spring 8 is installed on the fixing hole 64, and a top plate 81 is provided on the second spring 8. The top plate 81 contacts the screw 7. The cooperation between the second spring 8 and the top plate 81 makes the connection between the screw 7 and the screw hole 25 tighter, while absorbing vibration and preventing the screw 7 from loosening. If the screw 7 becomes loose, the second spring 8 will cooperate with the top plate 81 to push the screw 7 out of the fixing hole 64, so that the worker can clearly find the problem.

[0021] The working principle of this utility model is as follows: After the bolt 3 and nut 4 are inserted into the connecting hole 21 and assembled, the fixing plate 5 is inserted into the second mounting groove 23. Then, the locking plate 6 is inserted into the first mounting groove 22. The insert rod 63 passes through the slot 24 and enters the compression groove 54, so that the insert rod 63 pushes the locking block 52 to compress the first spring 53 into the slot 211. Finally, the screw 7 is inserted into the fixing hole 64 and the screw hole 25 to complete the connection between the locking plate 6 and the flange 2, thereby achieving the limiting and fixing of the bolt 3 and nut 4.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0023] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
